Two men, each handsome and unusually adept at his chosen work, embodied an element of the great dynamic that characterized America’s rush toward the twentieth century. The architect was Daniel Hudson Burnham, the fair’s brilliant director of works and the builder of many of the country’s most important structures, including the Flatiron Building in New York and Union Station in Washington, D.C. The murderer was Henry H. Holmes, a young doctor who, in a malign parody of the White City, built his “World’s Fair Hotel” just west of the fairgrounds.

The grandson and great-grandson of Chicago police officers, Chicago Police Detective James Sherlock was CPD through and through. His career had seen its share of twists and turns, from his time working undercover to thwart robberies on Chicago's L trains to his years as a homicide detective. He thought he had seen it all. But on this day, he was at the records center to see the case file for the murder of John Hughes, who was 17 years old when he was gunned down on Chicago's Southwest Side in 1976. The case's threads led everywhere.
